Delphi AS10317 Ignition Knock (Detonation) Sensor

Delphi AS10317 Knock Sensor Overview

Delphi AS10317 is an ignition knock sensor built for accurate engine feedback and OE-style replacement performance. It is a direct-fit sensor for select Mazda applications, including Mazda 3 and Mazda 6 models, with a 2-terminal pin design and a single oval connector.

Built to OE standards for calibration and signal accuracy, this Delphi knock sensor helps the engine control system detect detonation events and adjust timing as needed. The result is reliable sensor input for vehicles that depend on precise knock detection.

Key Features

• Part number: AS10317
• Ignition knock (detonation) sensor for emission control and engine management systems
• 2 terminals with pin-style connection
• 1 male oval connector
• OE-calibrated and validated for accurate readings
• Direct replacement for select Mazda 3 and Mazda 6 applications
• Package contents: ignition knock sensor only

Detailed Description

Delphi AS10317 is engineered for vehicles that rely on precise knock detection to manage ignition timing and protect engine performance. Delphi validates its sensors to OE standards, using development and calibration methods that support consistent signal output and reduced comeback risk. This makes AS10317 a practical choice for drivers and technicians servicing Mazda 3 and Mazda 6 models from the listed years.

This part cross-references Standard Ignition KS469 for the same application. The AS10317 part number is also commonly searched when sourcing a replacement knock sensor for 2018-2022 Mazda 6 and 2019-2022 Mazda 3 applications.

What It Helps Address

• Knock sensor fault codes
• Erratic ignition timing caused by inaccurate detonation feedback
• Engine pinging or spark knock concerns
• Check engine light conditions related to knock sensor performance
• Driveability issues tied to poor sensor signal quality

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. AS10317 uses a male oval connector with 2 male terminals and does not include mounting hardware. Confirm the vehicle application against the listed fitment for 2019-2022 Mazda 3 and 2018-2021 Mazda 6 before replacing the sensor.

Quality Assurance

Delphi tests and calibrates this sensor to OE standards and uses stringent product validation methods during development. That OE-focused process supports accurate readings and consistent performance in the vehicle’s knock detection system.
